Doubts regarding new coronavirus, which causes COVID-19 disease, are many. This new pandemic has caught everyone new and practically all countries have suffered from the virus, to a greater or lesser extent.

From various Centers for Disease Control and Prevention indicate that the incubation period for the virus ranges from two days to two weeks after exposure to it. That is, from the time you contract the disease until the symptoms begin. Along the same lines is a study published in the Annals of Internal Medicine, which ensures that these symptoms can appear from the fifth day, and people develop symptoms for twelve days.

What happens when the virus enters our body?

One of the main health recommendations during the pandemic has been that of wash your hands regularly and avoid touching your face, because through the mouth and airways is where the virus could enter our body. That’s where it affects first of all, both the nostrils and the mucous membranes in the back of the throat.

It is in the throat where, often, the first symptoms begin to appear, such as a strong sore throat or dry cough, in addition to fever, fatigue or muscle pain in the most severe cases. All this would be during the first day of incubation of the virus. Thus, according to a study published in the Journal of the American Medical Association, in which they analyzed 138 patients, the most common symptoms were fever (88% of cases), dry cough (68%) fatigue (38%), and cough with phlegm (33%). During the following days, the virus spreads to the lungs, which can make it difficult to breathe.

Second week with the virus in the body

During the second week with COVID-19 in the body is when respiratory problems are aggravated, as the membranes of the lungs begin to swell. This week would be when a person is hospitalized if she continues to have trouble breathing. According to the Journal of the American Medical Association, the cases studied were observed severe respiratory problems on the eighth day. In this second week, in addition, other symptoms may come, such as nausea, diarrhea, or indigestion. It is at this point when you can get death in case of organ failure.

Towards the end of the second week the most severe cases are admitted to intensive care, while those who have reacted well to the treatments see how fever is reduced and breathing improves. Generally, the estimated time for recovery is two weeks in mild cases and three and six weeks for the most severe.

He day 18 would be the critic according to the study, because in the most serious cases is when death can come. If it is overcome, the most serious cases could take up to a month and a half to recover.
